To all whom it may concern.-

Beit known that L ALBERT KoMP, of 'the city, county, and Stateof 'Newfork have invented a new and useful Improvement in Eye- "leting-Machines; and I do hereby declare the following to be a full, clear, and exact descripvtion thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying .drawin s formin part of this specification, in-

which-.- Figure 1 is a vertical section taken through the supplier of an eyeleting-machine made according to my invention. Fig. f2 is a front elevation. Fig. 3 is a detached view of the end of the supplier. Fig. 4 is a vertical section of the machine, taken in the line of the punching device. This View'A shows more clearly some of the. parts which are between the hopper-frame Q and the main frame A. Fig. 5 is a top or plan view, the hopper and feed compartment being shown uncovered. Fig. 6 is 4a horizontal section of a portion of the machine, taken in the line :u a: of Fig. 4. Fig. 7 is a cross-section of the lower end of the hopper, showing the feed-passages.

Similar letters indicate corresponding parts. This invention relates to machinery for applying eyelets and cylindrical fasteningsto paper, cloth, or other articles on which such fastenings can be used.

The letter A designates the frame of the machine, which may' be secured to a tablevor other article on which it is placed for opera- The bottom of the frame, at its front,

part rises a guide-pin, C, which extends above the level of the fixed die B to a distance about equal to the length of the eyelet or fastening to be used.

TheletterD designates the upper die, whose stock E moves in guides formed vin a projecting part, F, of the frame of the machine. The upper part of the stock is hollow, and contains aspring, H, whichbears against thehead of a lmovable pin, G,`whose Astem is fitted to move through the center Aof the die D, its end projecting below it, as shown in the drawings.

The face of the pin G is made concave to t `over the pointed end of pinG. The yielding piu G takes an eyelet fromthe end o; the'supplier and brings'it to and holdsI it ina'correctv position to enable itto pass downI over the fixed pin C, on which it is heldjwhil'e being acted on by the dies D and B. The die or plunger .D is moved by a lever, J, which is pivoted `to the frame, andwhich is provided .'with a weighted handle, K. The lever J and die-stock E'are connected byXmeans of a'bent arm, L, that projects from the 'stock and efxtends over the top of the lever in such a manner as to hold the lever 'to the die-stock loosely, asis. represented in the drawings, the top of the lstock E being rounded to allow a lfree movement of the joint. A L The letter M designates a vibrating hopper covered by a hinged lid, N. AThe -lower sidev or end of the hopper is provided with anum- ,ber of feed-passages through which the eyelets. v

are allowed to `pass into a feed--compartment,- O, which conducts them into the supplier l?. Thehopper, feed-compartment, and supplier are all connected to a single fra-me, Q, so that they move together as one piece, and the frame Q is pivoted to the frameA of the machine at R, so that it can vibrate thereon when itis operated by the` lever J. The feed-compartment Ohas a depth about equal tothe height of an eyelet, so that4 an eyelet canv only enter it through one of the feed-passages U, the

' depth of the compartment being less than-the diameter of the eyelet across its hanged end.`

The eyelets are caused to present themselves at the feed-passages U with their flanged ends' down by reason of the 'agitation of the hopper. Both the hopper and' the feed-compartment are arranged so as to incline downward toward;V the supplier, and the feed compartment is made with converging sides, which guide the eyelets' to the mouth of the supplierP at the lower end of the compartment. The feedcompartment O has a movable or hinged cover,

S, which is locked by a spring-holder,a,whose end is sprung into a hole, b, in the lowerside of the-hopper-' This cover enables me to get access to and to inspect the feedcompartment and correct any misarrangement or` ,cloggingv of the eyelets. The supplier P is made with a channel whose edges `c (one of.v which is" shown in Fig. 1) support the auges of the eyelet while its-body projects throughthe bot- .l tom of the supplier. in the same manner in which screws, blanks, tacks, and pins are fed, .and thesupplier is curved'or bent so. as tore-- verse the position ofthe eyelets' during their passage through it.

'Motion isimparted to the hopper-frame Q by the lever J through the agency of a stud, d, that projects from the inner side of said le- 4ver and enters an elongated slot, e, formed in theadjacent end of alink, f,whoseother end is pivoted to frame Q at the point gi. When the'studd, during the upward movement of the lever "J, when it isl clinching an eyelet, comesagainstthe outer orright hand end of the 'slot e, it causes the frame Qto swing upward until at the completion of the movement the hopper is brought to a horizontal position, which willlnaturally be accompanied by a jerk or jansufcient to throwthe eyelets on their broad ends and disengagc any eyelets that have clogged in the feed-passages U, so that they will -be ready on the next descent of the lever to presentthemselves in good -position at said passage.` rIhe hopper-frameQ descends by gravity when the lever"`J falls; but its descentis controlled during the rst part of the downward movement of the leverby a hinged stop, g,v

for another operation. `The supplier P is ar#y ranged on an incline, so as to allow the eye lets to slide down through it of. their own accord, and it is bent .during its course su.-

eiently to reverse the position of the eyelets and bring their smaller yends down, and its length and its construction are such as to bring its lower end below thedie or plunger D and its pinG- 4when said die has been'raised, at which time'the stud d of lever J .will be ont of contact with :the end ofthe slot e. The lower end of the supplier has -its back plate, i, cut' away, so as to expose from above that'eyelet whose ilangeis at `the bottom or end of the supplier, said eyelet being prevented from sliding out, of the ,supplier by two springplates, j `@which are secured to the outer edges ofthe supplier, and whose forward ends `are bent around its lower end until they almost meet in'kfrontof the channel-way of the supplier, where they arrest the flow of the eyelets; When the plunger-pin G descends and' goes throughthe lowermost eyelet, thesupplier is drawn` backby the'lever J, andthe pin G strips or draws the eyelet through the springs, which immediately 'close again, and

check the iow `of the eyelets'reinaining in the supplier.

Fig. 1 represents the machinewhen the plunger or die D has ,begufits descent,and its pin G is about toeng'age an eyelet, which 'operation takes place -in-the"'earlier Vpart of the upward 'movement of the -lever J," and be- *fore its stud d haslconie tothe end of the that slot, ,the hoppenframe Qv begins its up` wardjmvcment, and the supplier P is drawn away from the plunger or die D, leaving an'I eyelet-on the pin G, which pin comes down and passes throughthe eyelet which is at the the top' of pin C, with which it; articulates, when the plunger or die D continues to deof the. spring H of th'epin G, and said die I) then acts upon the eyelet and compels it to enter the hole made in the material and'to pass over the pin C until it meets the die B, when the eyelet becomes clinched betweenthe lower die, B,andthe' upperkdie, D." 'Ihe passages U, whereof 'there may be one or more, are made of a forni symmetrical with the eye` lets when standin'gup'ontheirbroad ends, and
